Using a Sticky Design Inspires Drone Hitchhikes, Flies, and Swims by Fish, Imperial College London

-
 A new drone design that uses hitchhiking to save power and flies in the air and on the water is now available for pre-order. The Imperial College London team, which includes experts in aerial robotics, has built a new drone that is capable of attaching to a wide range of wet and dry surfaces, of varying texture and shape, with battery-saving characteristics. Additionally, the drone is capable of self-adapting such that it may descend from the air and then swim in the water. Longer airborne and underwater observations are possible thanks to the drone's capacity to "rest" while hitchhiking. Professor Li Wen is the driving force behind the new drone technology, which was developed in association with Imperial College London and Empa.

Sender Reputation's Impact on Inbox Placement

-



The email sender reputation is basically an ISP score (internet service provider). This is assigned to an email sending corporation or organization – to domains and IP addresses. Various elements affect the scores (more on the following) and the scores decide whether or not emails reach to the inbox. A bad reputation leads to spam or automated flagging or removal of e-mails.

The reputation of email sending is an important factor in what email is going to the inbox, what email is going to the spam folder, what is deleted, and what is refused. It has a different reputation among ISPs. In the viewpoint of the ISP, there are several elements that decide what constitutes spam. If the ISPs discover that something is improper in their advertising, your reputation might alter quickly.

Delivery vs Deliverability:




The process of sending an email to the receiver from the sender can be split into two parts:

- The first part is termed “Email Delivery” and relates to the acceptance of or refusal of the message. The sender is authenticated by the recipient. The delivery message is accepted if the sender is authenticated and the mailbox is present.

- “Email Deliverability” is the next section. It is the position of the message when it is accepted. Received emails will be sorted and either land in the inbox or junk bin, based on several parameters.

The server of the recipient examines the IP address, the domain "Mail FROM" and the email domain and decides the e-mail address. There are some following things considered by the server of the receiver.

1- Reputation:
The server accepts a message to be delivered if the IP reputation is good. The message will be Greylisted if the IP reputation looks suspicious. For bad IP reputation, the server can block the message.

2- Authentication:
The receiving server examines whether or not the message is SPF and DKIM authenticated and DMARC passed. If the message fails to verify SPF or DKIM, the message is mostly placed in the spam folder. And in this case more filters apply to verify email.

If SPF and DKIM pass the message but DMARC fails, what happens to the message depends on the DMARC policy. If the DMARC check passes the message, it is based on additional rules or filters that the e-mail receiver determines its placement. A nice opportunity for such a message is in the Inbox.

The server filters millions of emails at the same time. Because it wants to receive only excellent and secure emails. It looks at the emails from the sender with hundreds of distinct criteria such as unique identifiers.

The unique identifiers which form the reputation of the sender are:

- IP reputation:
The IP reputation tells how much user wishes to receive emails by measuring bounces, spam, or undesirable bulk mails from a certain IP address.

- Domain reputation:
Domain reputation that measures verified domain email quality. You get real-time SPF, DKIM, and DMARC validity checks for your domains via the Uptime Monitor. IP reputation monitors that are included in the Uptime Monitor utility check against the most prominent public blacklists for the IP address(s) of your SMTP server.
